Abstract
Official abstract text for this publication.
An electric razor is provided with a linear actuator having a stator which includes an electromagnet and also having a moving element which includes a permanent magnet. The electric razor is also provided with an amplitude control unit and a control/output unit, which detect the amplitude and speed of the moving element on the basis of an induced voltage occurring in the winding of the stator as the moving element reciprocates, compare the detected speed and a formerly detected speed, and, according to the difference representing the result of the comparison, change a method for controlling the moving element.
First claim
Opening claim text (preview).
The invention claimed is: 1. A hair removal device comprising: a linear actuator that includes a fixed element, which includes one of an electromagnet and a permanent magnet, and a movable element, which includes the other of the electromagnet and the permanent magnet; a detection unit that detects at least one of movement, speed, and acceleration of the movable element; and a control unit that compares a detected value of the detection unit with a detected value obtained in t…
